It is like foursquare for TV shows, movies, music, comic books, regular books, wine, and more. You check-in when you are watching or reading something and it lets all your friends know what you are doing.

If you check into certain events or check into something a certain amount of times you earn a virtual sticker. Once you earn 20 virtual stickers you can request to have real versions of the stickers sent to your home. It was pretty easy to earn 20 and I already requested my first 20 stickers. FREE STICKERS!!! SWEET!!! hehe...
